Abstract: A mullion assembly includes a mullion rail and hot gas tube for preventing condensation on the mullion of a refrigerator/freezer. The mullion rail is rollformed of steel and includes complementary channels for retaining refrigerator and freezer liners. One of the channels includes an additional formed portion to accept and positively retain a hot gas tube in surface contact with a rear surface of a front wall of the mullion rail to provide acceptable heat transfer from the tube to the steel along the entire length of the mullion rail.

Title: Injection device
Inventor: MICHEL PETER
IPC: A61M5/24
Filed: 1993-02-12
Granted: 2005-04-19
Abstract: An injection device is disclosed, into which an ampule with a piston and an injection needle may be interchangeably set. It has an actuating arrangement essentially composed of an operating knob, a driving element, a guiding element and a driven member, preferably having a rod and a flange. The driven member is rotatably secured to the guiding element fixedly arranged in the device and seats with its thread in a female thread of the driving element that can be axially moved and twisted by manually operating the operating knob.      When the operating knob is twisted, the driven element is moved forward and pushes the piston forward during the following axial displacement, so that injection is the result. In the disclosed device, the fixed guiding element is located before that axially movable driving element. The length of the operating arrangement is therefore shorter than in state-of-the-art injection devices, so that a larger maximal dosis may be injected with a device having the same overall length. This device is useful for medical applications.

Abstract: An osteosynthesis plate system is particularly well adapted to securely fuse adjacent cervical vertebrae. The plates are adapted for mounting upon the anterior or posterior surfaces of the vertebrae. Plates for mounting on the anterior vertebral surfaces have a concave bone contacting surface and a bone screw locking mechanism integral with each screw hole. Moreover, the bone contacting surface of the plate has a plurality of bone penetrating protrusions to more securely affix the plate to bone. Plates for mounting on the posterior vertebral surfaces also have bone penetrating protections on their bone contacting surfaces. Such plates are formed so as to have a curved bone contacting surface that fs concave in the transverse azis of the plate and convex in the longitudinal axis of the plate. The screw holes of such plates are constructed so as to guide a bone screw along a desired angle to improve the anchoring of the screws in bone.

Filed: 1994-07-07
Granted: 1996-03-19
Abstract: ABSTRACT        Multi-mode waveguide filters are temperature compensated using dielectric material contained within at least one cavity of a filter. The variation in operating frequency of the filter that would otherwise result from changes in temperature is substantially balanced by a change in operating frequency with temperature caused by a change in a dielectric constant of the dielectric material so that the operating frequency of the filter remains substantially constant with temperature. The filter can have one or more dual-mode or triple-mode cavities. In a method of constructing and compensating a filter, the amount of dielectric material is selected so that the dielectric material does not resonate at the operating frequency of the cavity, the amount of dielectric material in the cavity being adjustable after each cavity is constructed. The cavity is operated with a fixed amount of dielectric material contained in the cavity for each mode and the change in operating frequency of the filter with temperature is determined. If the change in operating frequency of the filter is not at an acceptable level, the amount of dielectric material contained in the cavity for each mode is varied and the filter is operated through a range of temperatures to determine whether the change in operating frequency is then at an acceptable level. These steps are repeated until the change in operating frequency of the filter is at an acceptable level. When the change in operating frequency of the filter with temperature is at an acceptable level, these filters can be used in satellites without a temperature control system.

Abstract: A variable flow rate expansion valve designed for in-line installation in a fluid conveying conduit such as between the high pressure condenser and lower pressure evaporator of a refrigeration system includes an integrally defined restrictor disc and a closure disc for controlling the flow of fluid through the valve.  The restrictor disc has a first set of flow apertures and the closure disc a second set of flow apertures.  The closure disc is rotatably coupled to the fixed restrictor device in a plane parallel to the plane of the restrictor disc and perpendicular to refrigerant flow.  A manual, calibrated, incrementally adjustable actuator permits the positioning of the closure disc with respect to the restrictor disc so as to permit the flow of refrigerant through the valve to be manually adjusted, by a chnage in the registry of the apertures in the closure and restrictor discs, in accordance with varying operating conditions and requirements.

Title: Oscillometric blood pressure monitor with enhanced cuff pressure control
Inventor: MEDERO RICHARD
IPC: A61B5/022
Filed: 1996-01-11
Granted: 2007-06-12
Abstract: An automated sphygmomanometer in which the so-called "air effect" (a slow rise or fall in cuff pressure caused by step inflates or deflates) is substantially eliminated by deflating (inflating) the pressure cuff to a pressure lower (higher) than the target pressure, waiting a short time interval, and then inflating (deflating) the pressure cuff to the target pressure. The driving force that causes the air effect to settle out after a step inflate or deflate is proportional to the size of the step change in pressure and is thus greatest during the wait time before the pressure cuff is inflated or deflated to the target pressure. Once at the target pressure, the remaining air effect is counteracted by the incremental air effect introduced by the latter inflate or deflate so that the air effect cancels out. The techniques of the invention provide most improved results for large inflates and deflates of 20mm Hg or more or first deflates after a complete inflate of the pressure cuff where the air effects are most pronounced.

Title: Vibration damping apparatus
Inventor: MUTAGUCHI MASAO
IPC: E04B1/98
Filed: 1996-01-18
Granted: 2002-11-26
Abstract: A vibration damping apparatus includes a frame having a rail member and end plates at longitudinal ends of the rail member.  The frame is a hollow box-shaped element or a hollow tubular element.  The rail member defines a downwardly arcuate surface.  The frame is fixed on a vibrant structure.  A vibration damping body is movably located on the rail member such that it can naturally oscillate thereon upon vibrations of the structure.  An  energy of vibration of the structure is transferred to and absorbed by the damping body so that the vibration of the structure is attenuated.  By appropriately determining  a radius of curvature of the rail member, a natural period of the damping body is set to be equal to that of the structure.          First and second magnets are mounted on the end plates and third and fourth magnets are mounted on opposite end faces of the damping body.  The first and third magnets have the same polarity and the second and fourth magnets have the same polarity.  Therefore, a repulsive force is generated when the first and third magnets approach each other or when the second and fourth magnets approach each other.          Consequently, collision between the damping body and the frame ends is prevented.
